Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to a counterweight scraper for scraper conveyors. Background Technology

[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials within a trough. A scraper conveyor with adjacent intermediate troughs that can bend to a limited extent in the horizontal and vertical planes is called a flexible scraper conveyor. A working face conveyor with its body bent at a 90-degree angle at the intersection of the working face and the transport roadway is called a "corner scraper conveyor." In current coal mining faces, the scraper conveyor not only transports coal and materials but also serves as the running track for the coal mining machine, making it an indispensable main piece of equipment in modern coal mining technology. Continuous operation of the scraper conveyor is essential for normal production. Otherwise, the entire coal mining face will be shut down, causing a production interruption. The main structure and components of various types of scraper conveyors are basically the same, consisting of three parts: the head section, the middle section, and the tail section.

[0003] In addition, there are auxiliary components such as hydraulic jacks for moving the conveyor and chain tensioners for tightening the chain. The head section consists of a head frame, motor, hydraulic coupling, reducer, and sprockets. The middle section consists of a transition trough, middle trough, chain, and scrapers. The tail section is a device for returning the scraper chain. Like the head section, the tail section of a heavy-duty scraper conveyor also has a power transmission device, which is distinguished by its installation position as the upper head and lower head.

[0004] However, in actual operation, scraper conveyors often experience coal accumulation, which is time-consuming and labor-intensive to clean. In view of this, a counterweight scraper was designed to effectively clean the coal accumulation at the bottom of the scraper, reduce the jumping phenomenon of the scraper during operation, and achieve good coal cleaning effect. Utility Model Content

[0005] The purpose of this utility model is to provide a counterweight scraper for scraper conveyors, which solves the problem that in the actual operation of scraper conveyors, coal often accumulates on the machine, which is time-consuming and laborious to clean. In view of this, a counterweight scraper that can effectively clean the coal accumulated at the bottom of the scraper is designed, reducing the jumping phenomenon of the scraper during operation and achieving good coal cleaning effect.

[0006] This utility model provides the following technical solution: a counterweight scraper for a scraper conveyor, including a scraper, an installation groove is provided inside the scraper, a scraper is inserted inside the installation groove, two sets of circular grooves are provided inside the scraper, and a limiting mechanism for fixing the scraper is provided between the inside of the two sets of circular grooves and the outside of the scraper.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a counterweight scraper for a scraper conveyor, including a scraper 1, with two sets of mounting plates 102 fixedly connected to the bottom end of the scraper 1. Each set of mounting plates 102 has a fastener 103 installed at its top. The scraper 1 has an internal mounting groove 101, and a scraper 3 is inserted into the groove. By increasing the counterweight of the scraper 3, the jumping phenomenon of the scraper 3 during operation is reduced, resulting in good coal cleaning effect. The mounting plates 102 and fasteners 103 facilitate the installation of the scraper 1 and scraper 3 on the scraper conveyor. By installing the scraper 3 inside the scraper 1, the scraper 1 and scraper 3 can rotate to the desired position on the scraper 1. When the scraper is at the bottom of the conveyor, it is convenient to scrape and clean the coal at the bottom of the conveyor. Due to the setting of the scraper 3, the coal cleaning is not time-consuming or labor-intensive. At the same time, the counterweight of the scraper 3 is increased, reducing the jumping phenomenon of the scraper 3 during operation, and the coal cleaning effect is good. The left and right sides of the scraper 1 are fixedly connected to the limit frame 104. The limit frame 104 can limit the two sides of the scraper 3, making it convenient for the scraper 3 to be installed inside the scraper 1. The scraper 1 has two sets of circular grooves 105 inside. The limit mechanism 2 for fixing the scraper 3 is provided between the inside of the two sets of circular grooves 105 and the outside of the scraper 1. The limit mechanism 2 makes it convenient to disassemble or install and fix the scraper 3.

[0021] As one implementation method in this embodiment, such as Figure 2 and Figure 4As shown, the limiting mechanism 2 includes two sets of round rods 201. Both sets of round rods 201 are inserted from the outer side of the scraper 1 into the interior of each round groove 105. A round plate 202 is fixedly connected to the side end of each round rod 201, and an insertion rod 203 is fixedly connected to the side end of each round plate 202. Two sets of insertion holes 301 are opened on the side end of the scraper 3, and each set of insertion rods 203 is inserted into each set of insertion holes 301. A spring 204 is sleeved on the outer end of each round rod 201. A connecting plate 205 is fixedly connected between the side ends of each round rod 201. Side plates 206 are fixedly connected to the left and right side ends of the connecting plate 205. A bolt 207 is threadedly connected between the side end of each side plate 206 and the side end of the scraper 1. In practice, by removing each bolt 207, pulling the connecting plate 205 can drive each round rod 201. Each circular plate 202 and each insert rod 203 moves, at which point each circular plate 202 retracts against each spring 204, and the insert rod 203 leaves the insertion hole 301. The insert rod 203 no longer limits the insertion hole 301, and the scraper 3 can be pulled to disassemble it. When installing a new scraper 3, the limiting bracket 104 limits both sides of the scraper 3, making it easy for the scraper 3 to be inserted into the mounting groove 101 inside the scraper 1. At this time, each insertion hole 301 on the side of the scraper 3 is aligned with the position of each insert rod 203. After releasing the connecting plate 205, the spring 204 pushes against the circular plate 202 to rebound, driving the insert rod 203 to be inserted into the insertion hole 301, thus initially limiting the scraper 3. Then, the bolt 207 is installed between the connecting plate 205 and the side of the scraper 1, thereby completing the fixation of the scraper 3.

[0022] Working principle: By installing scraper 3 inside scraper 1, scraper 1 and scraper 3 can rotate to the bottom of the conveyor, which facilitates scraping and cleaning of the coal at the bottom of the conveyor. The setting of scraper 3 makes coal cleaning time-saving and labor-saving, and at the same time increases the counterweight of scraper 3, reducing the jumping phenomenon of scraper 3 during operation, resulting in good coal cleaning effect.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
